SUDBURY -- Greater Sudbury has its 69th COVID-19 case, Public Health Sudbury & Districts reported early Thursday evening.

A woman in her 30s tested positive July 21, the health unit said in a news release.

She has not been travelling and has not been in contact with anyone known to have the disease. She is currently self-isolating.

"Through contact tracing, public health will notify all close contacts directly," the health unit said. "If you are not contacted by public health, you are not considered a close contact."

The new case is a reminder that people still have to be vigilant, public health said, even as the city and province reopens.

This is the second new case this week, after a person under age 19 tested positive Monday.

"Although permissible for up to 50 people indoors and 100 outdoors, non-essential in-person gatherings of any size should be limited," the release said. "Community spread remains possible and is likely in Sudbury and districts. Limiting our contacts and in-person interactions as much as possible is critical in reducing transmission of COVID-19."

Unless people are from the same household or social circle, they should keep two metres (6 feet) apart and wear a face covering if distancing is not possible.

Face coverings must be worn in all indoor public spaces, and they must also be worn in other indoor spaces where distancing is not possible.

Close contact is permitted within “social circles” and among members from the same household. A social circle can only include up to 10 people and must always be with the same people. You can only belong to one social circle.
